Exemplary embodiment relates to the use of the ProSe discovery control that the signaling consumption of minimizing is carried out, and
The machine making radio resource in order to carry out ProSe discovery procedure and to be again allocated to UE
Can be able to be minimized.
In 3GPP RAN2, Class1 and type 2 resource allocation methods are identified.
In Class1 distributes, what D2D UE was transmitted from the system information block of broadcast automatic network is total to
Resource is found with resource pool obtains.Therefore, Class1 distribution can be applied to be in idle mould
Formula or the UE of connection mode.As a comparison, for type 2 distribute for, D2D UE with
Specific to the mode of UE, for the transmission of each discovery signal or the transmission of a series of discovery signal

Source distribution type is not the most reached a conclusion.
In view of above standardization background, especially when UE mobility is accounted for such as
What control ProSe find situation and coordinate ProSe find resource major issue should be able to
Solve.Such as, in some region, many UE are located adjacent one another and these UE are carrying out ProSe
May migrate between the different districts that different types of BS is covered while service,
Move to another community from a community at UE and other community, to set up ProSe
When ProSe found that resource and situation suitably manage find that resource is divided again to reduce
The chance joined and related signaling cost can be favourable.In order to be more fully understood that the disclosure, under
The exemplary architecture that can put into practice disclosure embodiment wherein will be described by literary composition.
Fig. 1 illustrates and wherein can carry out, with embodiment of this disclosure, the exemplary link put into practice
Structure 100.As it is shown in figure 1, framework 100 includes BS 1 and 2, they can be via this area
X2 interface known to the skilled person interconnects.As shown, BS 1 can be with honeycomb side
Formula communicates with each in UE 1-3, and UE 2 and 3 is owing to they are enough
Neighbouring and carry out ProSe D2D communication.Similar situation also appears at BS 2 and UE 4-6.
It should be noted that, the quantity of UE is only in order at exemplary purpose as illustrated here,
And covering power according to this BS can have many UE in the overlay area of BS.It addition, root
According to different embodiments, there may be in framework 100 and carry out for simplicity and not
The other entity of diagram.Such as, MME/S-GW entity can be with BS (that is, eNB)
It is attached thus UE is connected to CN and between BS and CN, forwards data.
It is in the UE 3 of idle pulley or connection mode is provided from BS 1 and quilt wherein
The community being depicted as ellipse is moved that provided to BS 2 and is depicted as ellipse equally
New community BS between in scene, can initiate in the new cell and another in this new community
The ProSe discovery procedure of individual UE (being such as depicted as the UE 4 close to UE 3).Although
The most clearly illustrate, but in BS in scene, UE 3 can be from a community
Mobile to another community, the two community is all serviced by BS 1, and UE 3 is permissible
ProSe discovery procedure is initiated in other community.Send out about the ProSe being used in new community
The resource of existing process, prior art is not moved about in view of the BS of UE or between BS
How to distribute or redistribute such resource when of dynamic property and provide any teaching.To this end, this
Disclosed embodiment proposes multiple method, and they will carry out discussing in detail also with reference to Fig. 2 and 3
And can be by the mobile context in being suitably applied to BS or between BS.
Fig. 2 be indicative icon according to disclosure embodiment from BS angle for ProSe
The flow chart of method 200.As shown in Figure 2, in step S201, method 200 is from least
One UE (UE 3 as shown in Figure 1) receives resource instruction, and it indicates by this at least one
UE is for the resource of ProSe D2D discovery procedure.Here utilization of resources instruction can be wrapped
Include from the uplink signalling message of UE to BS and before indicating at least one UE
Or presently used D2D finds resource, such as by the UE 3 in the overlay area of BS 1
The resource used.
In step S202, method 200 determines for being somebody's turn to do based on received utilization of resources instruction
At least one UE performs the resource of ProSe D2D discovery procedure subsequently.Although and not shown,
But in one embodiment, the determination of step S202 can include determining that the money at single BS
Source or be included between at least two BS coordinates so that it is determined that resource, and is determined
Resource at least partly indicate with this utilization of resources specified by resource the most overlapping.
As mentioned before, the solution that the disclosure is proposed can be applied in BS
Scene, and therefore can be at the current single BS carrying out the such as BS 1 serviced for UE 3
Place determines resource, and UE 3 move to the overlay area of BS 1 from a community another
It is that it determines resource during one community.Similarly, for scene between BS, this determines can
Coordinate so that it is determined that suitably to be included between two BS (such as, BS 1 and BS 2)
Resource.Here coordination can trigger via multiple actions or event and by various modes
Implement, such as by the Dedicated Signaling Channel through X2 interface.Resource determined by due to is extremely
Resource specified by small part and utilization of resources instruction overlaps, and thus be accordingly used in and sends out for ProSe
Probability or number of times that existing process execution resource is redistributed can be decreased obviously.Determined or assisted
The resource adjusted can be the time in time domain and frequency domain and frequency resource respectively.
At least one of which UE is in idle pulley or from least two BS one
BS moves in the embodiment of another BS to this at least two BS, and method 200 is permissible
Determine and determine resource is entered in received utilization of resources instruction in the case of community
Row is coordinated.In other words, for the UE of idle pulley, if there being D2D to find operation
Carrying out and its beacon resource (that is, finding the resource of operation for ProSe) is being based on
Community or specific to community, then may need the coordination between BS thus reduce resource weight
Newly assigned probability.It is to say, in order to support proposed mechanism, for idle pulley
UE for, the resource pool of multiple minizones should be to share or overlapping, or for not
Common source is there is with in those ponds of community.If the UE of idle pulley utilizes existence possible
The solution of conflict, be initially based on its UE mark and select beacon channel, then for phase
There is for adjacent cell identical or essentially identical resource pool and would is that the most sensitive.
At least one of which UE is transformed to another embodiment of connection mode from idle pulley
In, method 200 can determine based on utilization of resources instruction received in idle mode
Resource.Such as, if UE is transformed to connection mode, then beacon resource should be as much as possible
It is retained in this UE already in BS thereon.Till indicating it up to now to BS
The beacon resource used in an idle state, this UE can obtain the signalisation of this BS
To keep this beacon resource constant.After pattern or state transformation, if this UE switches to
Target cell, then it can retain existing beacon channel until detecting and solving possible
Conflict, this may have influence on the UE switched over or other UE being present in this community.
In worst case, because cannot use at least partly with the beacon resource used before
Overlapping resource, wherein this UE can be stationed thereon or this UE may cut to it
The BS changed can be that this UE redistributes new beacon resource.If it addition, BS pin
ProSe D2D discovery procedure is constructed resource pool, then it such as can be based in step S202
The determination that carries out and for IDLE/CONNECTED beacon, this pond is updated.
About resource pool, BS after coordinating can for the UE of corresponding idle pulley and
The UE of connection mode sets up the respective resources for performing corresponding ProSe D2D discovery procedure
Pond.But such deployment form is owing to the resource pool scope for beacon channel is the biggest adjacent
The possible case that beacon resource available in community is not enough relative to this beacon scope of resource.Cause
This, at least for active UE, resource pool carrying out between neighbor cell exclusive sharing will
It is favourable.By this way, each in multiple BS can be by central entities or logical
Cross the coordination between multiple BS and be assigned with two kinds of exclusive resource pond (one for sky
Not busy UE is then used for another enlivening UE).
In yet another embodiment, method 200 can be at least one UE from this at least two
A BS (that is, source BS) in BS switches to another BS in this at least two BS
By the ProSe D2D discovery procedure about this at least one UE time (that is, target BS)
Contextual information (or parameter) is sent to this another BS from this BS.By at source and mesh
The contextual information about finding is transmitted, for redistributing the letter of beacon resource between mark eNB
Cost is made to be saved.
Returning process, in step S203, method 200 notifies to this at least one UE with signal
Determined by for performing the resource of ProSe D2D discovery procedure.
Utilize the method 200 that can be performed as discussed in various embodiments above by BS
And version, resource determined by single BS or by least two BS it
Between coordination determined by resource at least partly indicate with this utilization of resources specified by resource have
Institute is overlapping, and makes to be allocated for resource that D2D finds with before or presently used
Those resources there is no significantly different, and therefore to perform D2D discovery and be that UE is the heaviest
New Resources allocation be probably unnecessary or it can be avoided that.Thus, the utilization of radio resource
The wireless signaling cost that efficiency can be improved and relevant resource is redistributed can decline.
Fig. 3 be indicative icon according to disclosure embodiment from UE angle for ProSe
The flow chart of method 300.As it is shown on figure 3, method 300 is from least one UE (such as,
UE 3 shown in Fig. 1) at least one BS (such as, BS 1 or BS 2 or its both)
The transmission utilization of resources indicates, and it indicates and was found for ProSe D2D by this at least one UE
The resource of journey.Here utilization of resources instruction can be identical with discussed in method 200
And therefore to simple and clear purpose and omit its further details.Subsequently, in step S302,
Method 300 from this at least one BS receive resource distribution instruction, its indicate for this at least one
For performing the resource of ProSe D2D discovery procedure subsequently determined by individual UE equipment.Should
Resource distribution instruction can such as step S203 in method 200 discussed by BS with letter
Number notify.Here resource determined by can have with method 200 discussed in those
